Estimated range and battery specs for Tesla Model 3 Mid-Range

Yesterday, Elon said the Model 3 Mid Range battery has fewer cells than the Long Range battery and is not a software limited version. But how many cells does it have? I decided to have a closer look. Luckily, Tesla has also released the weight numbers.

Step 1: The weight difference between MR and SR is 137 lb (62 kg).
If you open the Model 3 page here and scroll down to the Specs section, it shows 3,686 lb for MR. In comparison, the presskit page says 3,549 lb for SR. The difference is 137 lb (62 kg).

Step 2: 137 lb equals 768 cells
A Model 3 LR module with 23*46= 1,058 cells weighs 191 lb (source). Therefore 137 lb should equal to 759 cells but we need a number that’s a multiple of 96 because all Model 3 packs have 96 bricks. Therefore 759 is rounded up to 768.

Step 3: The MR pack has 2,976 + 768= 3,744 cells
The SR pack has 2,976 cells (source). If we add the 768 cell difference that we calculated, the Mid Range battery should have 3,744 cells.
